How we scored it
Root extract: terpenoids, sugars, phenolics and other plant constituents all n = 1; extraction solvent leaves no mass. Natural mass 100% = 1.00.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
